What is it about middle grade mysteries that is so enduring? Whether you were a devoted Nancy Drew or Hardy Boys fan, snuck around New York City with Harriet the Spy, or are exploring the genre for the first time with authors like Varian Johnson and Chris Grabenstein, there’s something for everyone in this genre. The great thing about middle grade mysteries is that they allow readers of all ages to put their puzzle solving skills to work, while also dialing back the gore and scares that are often hallmarks of mysteries for older readers. Populated with fun characters, unique settings, and fast placed plots, the book below are all great choices for this Read Harder Challenge. To start, I’ve listed a couple enduring classics of the genre before moving on to more current works.

As the inn fills up with a series of guests, each of whom has a story to tell and suspicions to arouse, objects begin to go missing and the secrets of Greenglass House begin to surface. This book continues to be a popular checkout in our library for both middle graders reading it for the first time and young adults eager to reread a book they love.
